Description

Technical Field

[0001] The utility model belongs to the technical field of valve sleeve inner end face depth step measurement, and particularly relates to a valve sleeve inner end face depth step size measuring device. Background Art

[0002] The valve sleeve is a component used to limit the range of motion of the valve ball, commonly used in deep-well pump valves. Its primary function is to ensure that the valve ball moves within a specific orbit, thereby controlling the flow of fluid. The design and material selection of the valve sleeve have a significant impact on its performance. It is typically manufactured using CNC turning or machining techniques, and materials such as AL6061 are used to ensure durability and precision. During the measurement process of the valve sleeve, it is necessary to measure the depth step size of the valve sleeve end face to determine the size of the depth step.

[0003] At present, the existing methods for measuring the depth step of the end face of the valve sleeve are mostly complicated, and the operation is cumbersome during use. The results obtained after measurement are not accurate enough and the measurement accuracy is not high. For this reason, we propose a device for measuring the depth step size of the end face of the valve sleeve. Utility Model Content

[0006] Preferably, a guide groove is provided on an outer side of the guide block, and a first bolt is provided on an outer middle end side of the guide sleeve, and the first bolt extends into the interior of the guide sleeve and into the guide groove.

[0007] Preferably, a bushing is provided on the inner wall surface of the top end of the guide sleeve, and the bushing is in close contact with the bottom end of the dial indicator.

[0008] Preferably, a second bolt is provided on the outside of one side of the top end of the guide sleeve, and the dial indicator is fixedly inserted into the inside of the guide sleeve through the second bolt and the bushing.

[0009] Preferably, a valve sleeve is provided at the bottom end of the guide sleeve, the valve sleeve is inserted into the interior of the guide sleeve, and the guide rod is inserted into the interior of the valve sleeve.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. By inserting the valve sleeve into the bottom of the guide sleeve, the guide rod is lifted up, and the thrust is transmitted to the measuring needle through the guide block, and then the micrometer is used to measure the depth step size of the end face of the valve sleeve. This design greatly improves the convenience of measuring the depth step size of the end face of the valve sleeve, making the operation more convenient and quick during use, and ensuring the measurement accuracy.

[0012] 2. By opening a guide groove on one side of the guide block and cooperating with the first bolt extending into the guide groove, the guide block can be more effectively limited, thereby improving stability during use and preventing the guide block from detaching from the guide sleeve under normal circumstances, thereby affecting use.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3The utility model provides a technical solution for a device for measuring the depth step size of the end face of a valve sleeve: it includes a guide sleeve 1, a guide block 2 and a guide rod 3. A guide block 2 is provided at the middle end of the inner part of the guide sleeve 1. The guide block 2 is fixedly arranged inside the guide sleeve 1. A micrometer 7 is inserted at the top end of the inner part of the guide sleeve 1. A measuring needle 9 is provided at the bottom of the micrometer 7. The measuring needle 9 extends to the top end of the inner part of the guide sleeve 1. The measuring needle 9 at the bottom of the micrometer 7 is inserted into the interior of the guide sleeve 1 and is in close contact with the top of the guide block 2. A guide rod 3 is provided at the bottom of the guide block 2. The guide rod 3 is fixedly installed at the bottom center position of the guide block 2 by a threaded connection.

[0019] Specifically, a guide groove 10 is provided on an outer side of the guide block 2 , and a first bolt 5 is provided on an outer middle end side of the guide sleeve 1 . The first bolt 5 extends into the interior of the guide sleeve 1 and into the guide groove 10 .

[0020] Specifically, a bushing 4 is provided on the inner wall surface of the top end of the guide sleeve 1 , and the bushing 4 is in close contact with the bottom end of the dial indicator 7 .

[0021] Specifically, a second bolt 6 is provided on the outside of one side of the top end of the guide sleeve 1 , and the dial indicator 7 is fixedly inserted into the inside of the guide sleeve 1 through the second bolt 6 and the bushing 4 .

[0022] Specifically, a valve sleeve 8 is provided at the bottom end of the guide sleeve 1 , the valve sleeve 8 is inserted into the interior of the guide sleeve 1 , and the guide rod 3 is inserted into the interior of the valve sleeve 8 .

[0023] In this embodiment, under normal conditions, the bottom end surface of the guide rod 3 is flush with the bottom end surface of the guide sleeve 1. At this time, the reading of the dial indicator 7 returns to zero. When measuring the depth step size of the inner end surface of the valve sleeve 8, the valve sleeve 8 is inserted from the bottom of the guide sleeve 1, and at the same time, the guide rod 3 inside the guide sleeve 1 is inserted into the interior of the valve sleeve 8, and then it is placed on a stable platform. The inner end surface of the valve sleeve 8 is in contact with the guide rod 3. When the valve sleeve 8 is inserted into the guide sleeve 1, the inner end surface of the valve sleeve 8 will push the guide rod 3 upward, so that the guide rod 3 drives the guide block 2 to move upward. The inside of the guide sleeve 1 slides upward. During the upward sliding of the guide block 2, the first bolt 5 is used to cooperate with the guide groove 10 to limit the guide block 2, thereby ensuring the stability of the guide block 2 during the sliding process. The upward sliding guide block 2 pushes the stylus 9 upward, and the telescopic distance of the stylus 9 is measured by the micrometer 7, thereby achieving the purpose of measurement and displaying the measurement data results. This design makes it more convenient and quick to measure the depth step size of the end face of the valve sleeve 8, simple to operate, and improves the measurement accuracy.
